Age - 29 *30 in April* Height- 5Ft 9In Weight- 255lbs This week was the first week I stopped drinking soda and my daily Redbulls. Everyday I have been going to the gym and riding the stationary bike for around 40-44 minutes @10-11 total miles daily. My heart rate while doing this activity stays at 135-155bpm. My daily calorie intake is around 1300-1500 calories, low I know. My plan next week is to incorporate some weight lifting after my time on the stationary bike. I just needed this week to kind of set a baseline/routine with actually going and the whole changing of my eating habits. Eventually once I drop some weight I want to start running again and really get into back into a point where I am happy with how I look. I am open to any and all pointers or even conversation about my low-ish calorie intake. I don't do anything else after my stationary bike session and sit behind a computer screen, so I was keeping my calories low by choice. It is currently day 4 and I really don't feel like I'm in a bad spot or anything. I have been getting headaches throughout the day but I suppose that is from the lack of soda and red bull. I used to drink 2-4 of the small cans of soda a day + a 12oz Redbull in the morning. I am hoping that with these 10 miles a day on the bike, lowering my caloric intake and cutting out soda/energy drinks I will start to see some gains. I drink around 5-8 bottles of water daily @16.9Fl.OZ If you have read all of this thank you for your time I hope to be an active member in this community! Much love everyone!
